En-14
■ 9.2-channel playback
By adding an external amplifier to the 7.2-channel
configuration, you can enjoy 9.2-channel playback.
Connect your power amplifier’s analog audio input jacks to
the AV receiver’s SB/FH/FW
*1 EXT AMP jacks with
audio cables. To use the SB/FH/FW EXT AMP jacks, you
must specify their channel with the “Preout to External
Amplifier” setting (
➔ page 64 ).
You can set which speakers you want to use by priority.
See “Selecting Speaker Layout” (
➔ page 52 ).

Attaching the Speaker Cable Labels
The speaker terminals are color-coded for identification
purpose.
The supplied speaker cable labels are also color-coded and
you should attach them to the positive (+) side of each
speaker cable in accordance with the table above. Then all
you need to do is to match the color of each label to the
corresponding speaker terminal.

Speaker Connection Precautions
Read the following before connecting your speakers:
• You can connect speakers with an impedance of between
4 and 16 ohms. If the impedance of any of the connected
speakers is 4 ohms or more, but less than 6 ohms, be sure
to set the minimum speaker impedance to “4ohms”
(
➔ page 63 ). If you use speakers with a lower
impedance, and use the amplifier at high volume levels
for a long period of time, the built-in protection circuit
may be activated.
• Disconnect the power cord from the wall outlet before
making any connections.
• Read the instructions supplied with your speakers.
• Pay close attention to speaker wiring polarity. In other
words, connect positive (+) terminals only to positive (+)
terminals, and negative (–) terminals only to negative (–)
terminals. If you get them the wrong way around, the
sound will be out of phase and will sound unnatural.
• Unnecessarily long, or very thin speaker cables may
affect the sound quality and should be avoided.
• Be careful not to short the positive and negative wires.
Doing so may damage the AV receiver.
• Make sure the metal core of the wire does not have
contact with the AV receiver’s rear panel. Doing so may
damage the AV receiver.
